Today something embaressing happened: a littlr old lady on my street asked me to cut her grass, and I said yes, but realised I didn't know how to. 🙈

Awww... I know it's embarrassing, but too often... we don't teach our children the simpler things. I determined my children would know how to make basic foods and meals for themselves, how to add gas to a car gas tank, how to do their own laundry, etc... it's such a list of things we mostly take for granted because we already know how without thought.
We all start somewhere. you have a kind and good neighbor. :)

That's ok you were helping her. I'm sure she is grateful that you are learning.

you've never cut grass before? Have you always lived in an apartment? Watch a youtube video
